New hints are emerging on the purpose of the Google “mystery barges” moored near San Francisco and Portland, Me.

San Francisco TV station KPIX says the barges will be invite-only, modular showrooms for Google to show off gadgets like Google Glass.

The station says the project was created at Google X, the search giant’s secretive research lab, where Google is working on self-driving cars and Glass among other projects. The station says the project is being overseen by Google co-founder Sergey Brin.

According to KPIX, the barge will include luxury showrooms and a party deck. The barge has been the subject of widespread speculation since it appeared in San Francisco Bay a few weeks ago, moored next to Treasure Island, roughly halfway between San Francisco and Oakland.

“It was an open secret that something big was being built,” says Larry Goldzband, executive director of the San Francisco Bay Conservation and Development Commission, who met with a Google employee and other company representatives twice this summer.

Goldzband says the Google team revealed little in those meetings. “There were very few specifics,” he says. He describes Google’s plan as, “We want to introduce technology to the Bay Area, but we don’t know where it will be or how long it will go. We can move it up and down the bay or go somewhere else.”

If Google is building a permanent structure or mooring its vessel for an extended period of time in the bay, it would need a permit from BCDC. While it is under construction Google does not need one says Goldzband. “For all I know, they’ll tow it away,” he says.

More details in the KPIX report below. The barges even have their own Wikipedia page.

Google didn’t immediately respond to a request for comment. Here is the KPIX report:
